A flavorful sirloin tip roast marinated in sherry, soy sauce, and oil, then roasted with mustard and thyme for a savory crust and finished with a rich homemade gravy.

Ingredients

  • 2 lb sirloin tip roast
  • 1 clove garlic, peeled and sliced
  • 1 tablespoon dry mustard
  • 2 teaspoons dried thyme leaves (or 1 tablespoon fresh thyme)
  • 1/3 cup dry sherry
  • 1/3 cup soy sauce
  • 1/4 cup vegetable or canola oil
  • 2 cups beef broth
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon dried thyme leaves (or 1 teaspoon fresh thyme)
  • Salt and freshly ground black pepper
  • 1 tablespoon cornstarch
  • 2 tablespoons cold water

Instructions

  1. Combine sherry, soy sauce, and oil in a dish or zip-top bag to make marinade. Add roast and garlic slices, coating well. Marinate in refrigerator for at least 4 hours or overnight.
  2. Preheat oven to 350°F (175°C).
  3. Remove roast from marinade, pat dry, and rub with dry mustard and thyme.
  4. Place roast on a rack in a roasting pan and cook until internal temperature reaches desired doneness (about 1 hr to 1 hr 15 mins for medium-rare at 135°F).
  5. Transfer roast to a cutting board, tent with foil, and rest for 15 minutes before slicing.
  6. For gravy, heat beef broth in a saucepan. Stir in Dijon mustard, thyme, salt, and pepper.
  7. Whisk cornstarch with cold water to make a slurry. Stir into simmering broth until thickened.
  8. Slice roast against the grain and serve with gravy.

Notes

  • Swap dry sherry with red wine for deeper flavor.
  • Use rosemary instead of thyme for variation.
  • Mix Dijon mustard with dry mustard for a stronger crust.
  • Add red pepper flakes to marinade for a spicy kick.
  • Leftovers make excellent sandwiches.
